‘Don’t know which is hotter!’

It’s been little more than a year since Sasha Mielczarek swept Bachelorette Sam Frost of her feet and declared his love for her amid a romantic New Zealand setting.

But the love this couple shares just keeps growing stronger by the day, with the pair unable to resist gushing about one another at every possible opportunity.

Taking to Instagram, Sash posted a photo of his biker babe sitting comfortably on his Harley Davidson motorcycle – though the cheeky reality star couldn’t resist having a bit of a light-hearted laugh at his girlfriend’s expense in the process.

‘Went home earlier this weekend and took this picture of the old girl! Oh and my 1974 Harley Davidson Shovel,’ he wrote, along with the hashtags #dontknowwhichishottertheflamesormysmokinghotgirlfriend #loveyoubabe

The pair recently got back from a romantic holiday in Bali, where they celebrated their one-year anniversary – which coincidentally comes just weeks before the premiere of the new season of The Bachelor, which kicks off on Wednesday night.

With Sam’s rejected suitor Richie Strahan in the hot seat this time around, Sam insists she’s done her research and can already predict who will win the WA-based rope access technician’s heart.

‘I’ve done a lot of research on this,’ Sam told listeners of her 2DayFM breakfast show, Rove & Sam, as they were joined by The Bachelor and The Bachelorette host Osher Gunsberg on Tuesday. ‘I think Richie chooses Megan.’

Megan Marx is a 27-year-old blonde beauty not too dissimilar from Sam herself – though working even more in her favour is the fact she is from WA as well.

Sam put her detective skills down to the fact the statuesque beauty features heavily in the promo clips for the show, while the music that accompanies her introduction clip is also ‘soft and romantic’ so that viewers fall in love with her too, Sam explains.

The 27-year-old hails from Richie's home state of Western Australia, which will certainly work in her favour
